Thanks to the ever growing team of developers who are contributing to make the !MapGuide Open Source project a more self-sustaining project.  

Please [wiki:SubmitTicket report any defects].

== Compatibility ==

MGOS 2.4.0 is compatible with [http://fdo.osgeo.org/content/fdo-370-downloads FDO 3.7.0].

== FDO ==

FDO is compiled against the Oracle 11.2 instant client available from [http://www.oracle.com/technology/software/tech/oci/instantclient/index.html?rssid=rss_otn_soft Instant Client Downloads].  For a Linux installation, the Oracle shared library path should be included in LD_LIBRARY_PATH or ldconfig.

== Installer notes ==

Installing MGOS 2.4 preview alongside MGOS 2.2 or older releases is not a currently supported configuration

Please observe the updated software requirements if you are using .net and/or IIS configuration:

 * IIS (all versions) require FastCGI to be installed. See [http://www.iis.net/download/FastCGI this link] for more information
 * The supported .net Framework version for the MapGuide .net API is 4.0
   * For IIS6 and below, the installer will still set the ASP.net version to 2.0.50727. You will have to manually change the ASP.net version to 4.0.30319 post-install

To assist new MapGuide users and developers, the installer also now bundles the following optional components:

 * .net/PHP/Java viewer samples
 * MapGuide Developer's Guide in HTML format with updated content
 * .net/PHP/Java Developer's Guide Samples

All bundled samples require the [http://download.osgeo.org/mapguide/releases/2.0.2/samples/Sheboygan.mgp Sheboygan dataset] to be loaded into the MapGuide Server. For Developer's Guide samples, the developer's guide data package needs to be loaded. These can be found in the root directories of the respective devguide samples in your MapGuide Web Tier installation.

Finally, due to coordinate system dictionary paths no longer tied to a global environment variable (RFC 122) a mandatory system reboot after installation is no longer required for all supported versions of Windows. However, a restart of Apache and/or IIS may be required for PHP to work.

== Known Issues ==

 * The installer will not remove the IIS virtual directories correctly if you specified a different virtual directory in IIS. For example, if you install with a virtual directory of "mapguide24" it will still remove the "mapguide" virtual directory on uninstall. 
 * An asp.net security setting prevents selection XML from being set from the .net viewer (#1984). The current workaround is to add the following line to web.config for the mapviewernet directory under the {{{<system.web>}}} configuration section:
{{{<httpRuntime requestValidationMode="2.0" />}}}
 * PHP Viewer and Developer's Guide samples will not work if the PHP viewer feature is not enabled. Likewise for .net and Java. Nothing in the installer will prevent you from making such a choice.
 * For the IIS configuration or Bundled configuration with a custom http port, you will have to update the WFS and WMS server name configuration properties via the MapGuide Site Administrator after installation if you intend to use such features. This is currently set to localhost:8008 for both.

== API changes ==#ApiChanges

[wiki:MapGuideRfc110 RFC 110] A new API for rendering performance profiling

[wiki:MapGuideRfc114 RFC 114] A new API for transaction save points

== New Server Configuration (serverconfig.ini) Options ==

[wiki:MapGuideRfc122 RFC 122] introduces the MentorDictionaryPath configuration property, which is the first place MapGuide Server will look for the coordinate system dictionary files. The MENTOR_DICTIONARY_PATH environment variable will be used instead if the specified path in serverconfig.ini does not exist

== New Web Configuration (webconfig.ini) Options ==

[wiki:MapGuideRfc122 RFC 122] introduces the MentorDictionaryPath configuration property, which is the first place the MapGuide Web Tier will look for the coordinate system dictionary files. The MENTOR_DICTIONARY_PATH environment variable will be used instead if the specified path in webconfig.ini does not exist

== Disk Space ==

The installer requires at least 1.5GB of disk space on C: during installation. Otherwise installation may not proceed.

If you do not have sufficient space on C:, you can open the installer file with [http://www.7-zip.org 7-zip] and extract the contents to another drive, and run the extracted setup.exe from there.  It may also be helpful to set your TEMP environment variable to a different drive.
